Color Conversion for all Elements

[KUMARARAJA@adobeforums.com]

Hi,
I am writing some plug in which can convert Color of the PDF for that i have used "PDDocColorConvertPage" it is perfectly working well for Grayscale Conversion, But the same method is not working for the Pantone (SpotColor) to CMYK conversion, so i tried with PDColorConvertPDEElement but i don't get the proper sample to use that function. I was blocked, please help me out to find the best method for color conversion problem.

Regards,

What do you mean it is "not working"? Please explain.

also, what version of Acrobat are you using?

[KUMARARAJA@adobeforums.com]

I am using Acrobat 9, Here i am giving the code which working now, in that my objective is to change all the elements to Grayscale, but i am sure that i did some mistakes, Please let me know where i made the mistake

Code:
-----
AVDoc avDoc = AVAppGetActiveDoc();
char str[256];
ASPathName aoPDFPathName = NULL;
char* OutputPdfFileName = "C:\\Output.pdf";
ASText pathText = ASTextNew();
ASFileSys aoFileSys = NULL;
pathText = ASTextFromScriptText(OutputPdfFileName, kASRomanScript);
aoFileSys = ASGetDefaultFileSysForPath(ASAtomFromString("ASTex tPath"), pathText);

if(avDoc==NULL)
{
sprintf(str,"There is no PDF document loaded in Acrobat.");
}
else
{
PDDoc pdDoc = AVDocGetPDDoc (avDoc);
int numPages = PDDocGetNumPages (pdDoc);
ASInt32 ai, aiNumElems;
PDEContent aoPDEContent = NULL;
PDEElement aoPDEElement;
PDPage aoPage = NULL;
aoPage = PDDocAcquirePage(pdDoc, 0);
aoPDEContent = PDPageAcquirePDEContent(aoPage, 0);
aiNumElems = PDEContentGetNumElems(aoPDEContent);
sprintf(str,"The active PDF Page has %d Elements.", aiNumElems);

AC_Profile prof;
ACProfileFromCode(&prof, AC_Profile_DotGain15);
for (ai = 0; ai < aiNumElems; ai++) { aoPDEElement = PDEContentGetElem(aoPDEContent, ai); PDColorConvertPDEElement(pdDoc, aoPDEElement, prof, AC_UseProfileIntent, true); } if (aoPDEContent != NULL){ PDPageReleasePDEContent(aoPage, 0); } // inform the user if we have done a color conversion. if(ASBoolToBool(gbConverted) == true) AVAlertNote("Color transform has been done to Gray"); else AVAlertNote("No color transform was made.");

aoPDFPathName = ASFileSysCreatePathName (aoFileSys, ASAtomFromString("ASTextPath"), pathText, 0);
PDDocSave (pdDoc, PDSaveFull | PDSaveCollectGarbage | PDSaveLinearized, aoPDFPathName, ASGetDefaultUnicodeFileSys(),NULL, NULL);
PDDocClose (pdDoc);
ACUnReferenceProfile(prof);
}

Thanks,

I don't want to read your code - I want to understand why you think that it's not working for spot/pantone colors.

[KUMARARAJA@adobeforums.com]

Still Spot color is present in the Output PDF file which i am saving, Convertion is not done from Pantone to CMYK, that is why i am thinking that some thing is missing while using PDColorConvertPDEElement.

[Leonard_Rosenthol@adobeforums.com]

You need to set/pass the correct color conversion params

[KUMARARAJA@adobeforums.com]

I am getting This error

"There is no source code available for the current location."

while the debugging the code

"PDColorConvertPDEElement(pdDoc, aoPDEElement, prof, AC_UseProfileIntent, true);"

What is the problem?

but in the same plugin PDDocColorConvertPage function is working fine.

[Leonard_Rosenthol@adobeforums.com]

Right - you don't have the source code to the PDFLibraries and as such you can't debug into that API call.

[KUMARARAJA@adobeforums.com]

So, PDColorConvertPDEElement is not for Acrobat SDK?

but in the Help i found

PDColorConvertPDEElement ()
Product availability: Acrobat, PDFL
Platform availability: Macintosh, Windows, UNIX

If it is not for Acrobat, then through which method i can change the color of the each elements?

Please direct me.

Thanks
